Answer:
Explanation:
Given
Volume of fixed chamber
Initial Temperature
Final Temperature
Heat Supplied
From First law of thermodynamics
Change in internal energy of the system is equal to heat added minus work done by the system
as the volume is fixed therefore work
thus
for mono-atomic gas is
and 1 mole contains
thus No of molecules
No of molecules
Answer: The correct answer is (C).
Explanation:
Supply function:
Demand function:
S(p)=D(p), price for which supply is equal to demand:
After solving this above equation graphically, we will get the values of p.
1) p =96.236
2) p=( -118.258)
We will reject the negative value of p.
So, the value of p that price for which the supply equals the demand is $ 96.236 $96.24. Hence, the correct answer is option (C).
Average speed = (distance covered) / (time to cover the distance)
= (30km + 40 km) / (25min + 35min)
= (70 km) / (60 min)
= 70 km/hour
